Patented Oct.u 5, 1929.

To all 'wtom it may concer-a:

Be it known that I, ROBERT IIIRD CLARK, of the city of Winnipeg, Province of Manitoba, Canada, have invented certain new and useful Improvements in lVheels, of which the following is the specification.

'Ihe invention krelates to improvements in wheels, particularly automobile and truck wheels and the object of the invention is to provide a non-puncturable, easy riding resilient wheel which can be readily assembled or dismounted and which is constructed to take up the various thrusts, both lateral and vertical to which it may be subjected.

With the above object in view the invention consists essentially in a hub,oppos ing spaced side yplates secured to the axle and provided with spaced concentrically arranged channels, a d isk surrounding and spaced from the hub and positioned centrally between plates and provided with concentrically arranged channels opposing the former channels, rings of resilient material inserted between the disk and the plates atthe channels, fastening bolts connecting the side plates and passing through suitably positioned openings provided in the edge of the disk, the parts being arranged and constructed as hereinafter more particularly described and later pointed out in the appended claim, reference being had to the accompanying drawing, in which Figure 1 represents a side view of a wheel constructed in accordance with my invention and with the lower half of the side plate removed to expose interior construction.

Fig. 2 representsA an enlarged transverse sectional view through the wheel.

Fig. 3 represents a transverse sectional view through the half of a wheel and show# ing a modified form of the invention.

In the drawing like characters of reference indicate corresponding parts in the several figures.

1 represents the hub of the wheel which is cast with a pair of spaced outstanding cir- .cumscribing flanges 2 and 3. 'Io the Hanges I secure such as by bolting, as indicated at 4: and 5,7a pair of spaced circular side plates 6 and 7 which are provided with opposing concentrically arranged channels 8, 8'w 9, 9', 10 and 10', these being formed in the present instance by rolling or casting the chan-` l nels in the plates, depending on whether they are sheet metal or cast.

application led October 8, 1917. Serial No. 195,421.

11 and 12 through which the outer edges ofthe plates are fastened together by means of bolts 13. These plates form a casing which supports in a resilient manner a central disk 14: provided with a central opening 15 entirely free of and surrounding the hub and with suitably positioned circularly arranged openings 16 admitting of the fastening at the bosses, it being noticed that there is ample clearance provided by the-se openings to allow of the movement of the disk in respect to the plates. Channels 8X, 9X and 10X are also formed on the faces of the disk directly opposing those of the plates.

rIhe disk is resiliently suspended from the plates by rings of resilient material 17, 17', 18, 18', 19 and 19 interposed between the opposite sides of the disk and the plates and. positioned in the channels. These rings are are positioned concentric to the hub and Vare preferably formed from rubber.

In building` the wheel it is desirable to have a slight compression in these rings by jamming the plates on them when they are bolted up. This serves positively to hold the rings and prevent any slip or creeping between the disk and the rings or the side plates and the rings.

Here I wish it to be noticed that the vchannels 8, 8', 9, 9', 10 Vand 10 are relatively deep, are wider than the rings, and have their sides beveled, while the channels 8", 9x and 10X are relatively shallow and are not larger than the rings. This arrangement permits of the tight fitting or hugging of the rings by the channels 8X, 9x and 10X to prevent any movement or bending of the rings at :this point, while it allows a lateral movement or bending of the sides of the rings in the lchannels 8, 8', 9, 9', 10 and 10'.

rI`he outer edge of the disk, which, it will be observed, extends beyond the outer edges of the plates, carries the wheel tread 20 which is preferably formed from rubber and is held in position by lapping clamping ating ony the road all the various stresses,-

Will be absorbed by the rings which Will take up not only vertical out lateral shock.

The openings l5 and 16 obviously allow of the free play of the disk inwardly and outwardly.

While the device has been shown with the side flanges liXed and the disk lioating it Will be readily understood that the reverse construction could be employed Without departing in the slightest from the spirit or' the invention.

In such an arrangement the disk Would simply extend to and be fastened to the hub and the side plates would be entirely free of the hub and Would carry the tread. Such an alternative arrangement is shown in section in Fig. 3 where a half or' the Wneel appears. In this figure the stationary disk is indicated at 14', the tica-ting side plates at 6 and 7 and the tread at 20. the tread being mounted directly on the plates which are brought together at their outer edges.

What I claim as my invention `is:-

A resilient Wheel comprising a nulo. similar spaced opposing side plates permanently secured to the hub and provided with spaced foncentrically arranged beveled channels, a loating disk interposed centrally between 'he side plates and provided on its opposite faces with concentrically arranged channels `)pposing the channels of the plates7 rubber ike concentrically arranged rings interposed `ietween the disk and the side plates and `:cated in the channels thereof7 the channels it the disk tightly hugging the rings but ne channels ot' the plates permitting slight relative lateral movement of the sides of the sings. bolts connecting the side plates, said iolts passing freely through suitable open- Yngs provided in the disk and a resilient read carried by the circumference of the iisk.

Ligned at Winnipeg, this 15 day of August. i917.
